VALVE.

SPECIFICATION forming part of Letters Patent No. 717,927, dated January6, 1903.

' Application filed September 19,1902. Serial No. 124,021. (No model.)

t.'0 all whom, it rita/y concern.-

Be it known that I, HENRY RITTER, a citi-V zen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Valves, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification.

The object of my invention is to provide a valve, particularly adaptedfor use in watercolumns attached to boilers, for giving an alarm bymeans of a steam-whistle both when the water reaches its maximum leveland its minimumrlevel*that is to say, both a high- Water alarm and alow-water alarm-though said valve may be used for other purposes, andthis objectI attain by means of simple and eiiicient mechanism, ashereinafter set forth.

The novelty of my invention will be specically pointed out in theclaims.

In the accompanying drawings, Figure l is a central sectional sideelevation of a valve embodying my invention. Fig. 2 is a plan view ofthe same. Fig. 3 is a central sectional side elevation of the valveunder a modified form of construction. Fig. 4.- is a plan View of Fig.3. Fig. 5 is a perspective View of the valve-stem-lifting mechanism ofthe valve shown in Figs. 3 and 4.. Fig. 6 is a central sectional sideelevation of a water column equipped with its float, whistle, and myimproved valve mechanism applied thereto.

The same letters of reference are used to indicate identical parts inall the iigures.

In Fig. 6 I have illustrated my valve as connected with the water-columnof a boiler and 4o have sufliciently indicated all of the connections toenable those familiar with the art to understand the application of thesame, so that in describing this figure `it is only necessary to saythat A is the water-column; B, the float therein; C, the stem of thefloat, with collars tt thereon above and below the eye of thevalve-lever I), through which the stem C passes. This eye is clearlyillustrated at b in Figs. 2 and 4. The valve-case E is secured 5o in thechannel c, leading from an aperture .controlled by the valve to thealarmwhistle Fat the outer end of the channel. This much of themechanism is old and common to the art and needs no further description.

By reference to Figs. 1 and 2 my preferred 55 form of valve mechanismmay be described as follows: The valve-casing E has an enlarged bore din its upper end, which at its lower end communicates with a smallerconcentric bore e, passing through a transverse passagef, communicatingwith the interior of the water-column, and finally terminates in aneedle-valve seat g in a passage h, leading through the valvecasing tothe channel c. The lower end of the valve-casing is threaded, as at t',to enable it to be screwed into the interiorly-threaded inner end of thechannel c, Fig. 6.` Fitted within the bore dof the valvecasing is alifting-cylinder G, extending above the top of the valve-case E andprovided with outwardly-projecting trunnions j, engaging notches in thehead-piece H of the actuatingleverD. This head-piece has on oppositeedges ribs bearing upon the upper ,surface of the valve-casing E, whichact as fulcra to enable the head-piece to be tilted on the top of thevalve-case by the action of the lever D, as will be readily understood,and when sotilted the cylinder Gr will be raised or lowered in itsbearing in the casing E, as will be readily understood. Within thecylinder Gis a valve composed of the lower frusto-conoidal or needleshaped valve g, an upper extension m therefrom passing through the boreeandthrough a perforation in the bottom of the cylinder G, and a stillfurther enlarged upper extension I iitting snugly within the cylinder G,and, if

desired, above the same a smaller stem n, by

which the valve can be readily removed from or replaced within the.cylinder G.

By the above construction it will be readily understood that theoperating-lever takes hold of the valve-stem low down or near its seat,so that in lifting or lowering the same a more direct up-and-downmovementis given to the valvestem than if the lever engaged the samedirectly at its upper end. Consequently there is less liability ofbinding, and a more sure and delicate action of the parts is insured.

In Figs. 3, 4, and 5 I have represented a modification in the structurewhich without IOO altering at all the principle of operation eheapensthe structure somewhat. Under this form the cylinder G is dispensed withas such, though its operatingbottom 0 is retained in the form of a ringwith ribs lo, Fig. 5,- engaging notches on the under side of theenlarged portion Gr of the valve-stem and with side arms r extending upin slots in the sides of the stern Grand having at their upper ends thetrunnionsj, engaging the recesses in the upper side of the head-piece Hof the lever D. In all other respects the Construction is the same andthe mode of operation is the same, as will be readily understood.

In order to aid the stem C of the fioat in maintaining the lever D andits head-piece H in proper operating position at all times, I employ alug J, projecting up through a slot in the head-piece H on its sideopposite the lever D.

Having thus fully described my invention, I clairn- 1. The combinationof a valve-ease, a valvestem vertically mounted therein and having atits lower end a tapering valve-point adapted to seat in theegress-aperture of the valvecase, a collar surrounding said stem andengaging therewith at its lower end, upward eX- tensions from saidcollar, a lever -actuated head-piece on the top of the valve-casing, andtrunnion eonnectionsbetweensaid head-piece and the upward extensions ofthe collar, substantially as described.

2. The combination of a Valve-ease, a valvestem vertically mountedtherein and having at its lower end a tapering valve-point adapted toseat in the egress-aperture of the valvecase, a cylinder surroundingsaid stem and engaging therewith at its lower end, a leveractuatedhead-piece on the top of the valvecasing, and trunnion connectionsbetween said head-piece and the upper end of the Cylinder, substantiallyas described.

HENRY RITTER.
